The AHE and CME coefficients are calculated from the following expressions [1]}
\(\sigma _{ab}=\lim _{q_0 \rightarrow 0}\frac{1}{iq_0} \lim _{q \rightarrow 0}\Pi _{ab,R}^{ant}(q_0,q)\nonumber \\\alpha =\lim _{q \rightarrow 0} \epsilon _{abc}\frac{1}{2iq_c}\lim _{q_0 \rightarrow 0}\Pi _{ab,R}^{ant}(q_0,q)\)
